Dr. Junzhong Xu, director of Cancer Imaging Research at the Vanderbilt University Institute of Imaging Science, discusses the development of MR cell size imaging1 utilizing diffusion MRI. The imaging technique provides real-time data on cell size, density and membrane permeability and gradient strength is crucial for accurate measurements. The technology's ability to differentiate recurrent brain tumors from radiation injuries and track cell changes associated with chemotherapy-induced apoptosis is groundbreaking. Watch this video with Dr. Xu to learn more.
Our ability to detect accurate mean cell size in tumors relies on the gradient strength we have. The stronger gradients we have, the more accurate and reliable measurements we can make.
